GCr15钢表面脉冲激光氮化研究
STUDY OF LASER NITRIDING ON THE GCr15 STEEL SURFACE
【摘要】 利用Nd:YAG固体脉冲激光对GCr15钢样品表面进行了激光氮化处理,获得了高硬度、高耐磨损、表面致密均匀的氮化铁改性层,并对改性层进行了XRD谱分析和表面及剖面显微形貌分析、表面硬度及硬化深度和磨损率等的测量。同时对GCr15钢表面激光氮化机理进行了分析和研究。
【Abstract】 Pulse laser nitriding of GCr15 steel was studied.The experimental results show that a high hardness,good wear resistance,compact and uniformity hard layer of iron nitride was obtained.The microstructure,phase constitution,micro-hardness,depth and wear properties of the layer were determined and analyzed,and the pulsed laser nitride mechanism on the surface of GCr15 steel was discussed.
